How can I get the autoincremented id when I insert a record in a table via jdbctemplate

由 ↘锁芯ラ 提交于 2019-11-29 01:42:46

Is there a way to get this auto incremented ID back at the time of the insertion. So in this example the return value of my method would be int Check this reference. You can use jdbcTemplate.update as: EDIT Added imports as asked import java.sql.Connection; import java.sql.PreparedStatement; import java.sql.SQLException; import org.springframework.jdbc.core.JdbcTemplate;

Unit testing a DAO class that uses Spring JDBC

由 ﹥＞﹥吖頭↗ 提交于 2019-11-29 01:19:48

I'm using Spring's JdbcTemplate to run the actual query (via a prepared statement) and map the results to the model object (via the RowMapper class). If I were to write unit tests, I'm not sure how I would/should mock the objects. For example, since there are only reads, I would use the actual database

Inserting multiple rows using JdbcTemplate

由 那年仲夏 提交于 2019-11-29 00:53:46
问题 How can I execute the following SQL in a scalable way using JdbcTemplate running on mySQL. In this case, scalable means: Only one SQL statement is executed on the server it works for any number of rows. Here's the statement: INSERT INTO myTable (foo, bar) VALUES ("asdf", "asdf"), ("qwer", "qwer") Assume that I have a list of POJO's with foo and bar fields. I realize that I could just iterate over the list and execute: jdbcTemplate.update("INSERT INTO myTable(foo, bar) VALUES (?, ?)", paramMap
